Tonight I imported photos into iPhoto from a Canon Rebel T2i, and the large previews look fine the first time I scan through them. But then if I run through them again some (not all) end up with what looks like a dark green overlay on them.

 

I've been using this camera and iPhoto for a couple of years now. This is a first. I'm shooting RAW (CR2), so I'm guessing the iPhoto RAW processor got borked in an update recently.

 

Saw similar issues in the forum from people using Aperture. Tried a few of their suggestions to no avail. Anyone else running into this with iPhoto?

    Have you enabled "highlight tone priority" in your Canon camera? The mac raw conversion does not handle this feature, and so the camera generated jpegs will reflect the highlight tone priority, but the developed raw image will not.

     

    If you have been using this feature, turn it off and try again.

    Thanks for the response, leonie. Highlight Tone Priority is turned off. (I didn't know what it was until I googled it just now.)

     

    I just uploaded another batch of photos to iPhoto. Everything looked fine after the import, thumbnails and large images all looked great. However when my wife opened that event again today, they're all green again.

    Tried "reprocess raw" on each image in iPhoto with no luck. Then I selected all the thumbnails in the event and reprocessed raw on all of them, and the green cast is gone!

     

    We'll see what happens on the next import...
